The storms had moved out of the state Wednesday morning after at least three tornadoes touched down in central and southern Oklahoma Tuesday, the National Weather Service said Wednesday.

The one that hit Lone Grove at about 7:30 p.m. had an intensity of EF4 and winds of around 170 mph.

The Enhanced Fujita scale measures the intensity of a tornado and its wind speeds based on the type of damage caused and rates it between EF0 and EF5.

The first tornado, which hit Edmond between 2:30 p.m. and 3 p.m., had an intensity ranging between EF0 and EF2, the NWS said. The service has not been able to determine an intensity for another tornado that hit near Langston about an hour later.

"We're just trying to get stuff in people's hands," store owner Matt Wilson told CNN while handing out pry bars and flashlights to residents at his hardware store in Lone Grove, where heavy damage occurred. "But just about all of Lone Grove is without power."View a map of where tornadoes touched down »
